Radio frequency receivers (RF receivers) are electronic components that process radiofrequency signals in order to use them in communications and waveform detection systems. The features and specifications of the RF receiver depend on its type. Examples of applications of radiofrequency receivers include military radar systems, medical imaging, remote sensing and satellite communication systems.

ATA5723CP3-TKQY

Application Field

ATA5723CP3-TKQY is an RF receiver designed for use with automotive applications. It is used for remote keyless entry systems (RKEs) and tire pressure monitoring systems (TPMSs) among other vehicle applications. It is ideal for long-range applications, and its operating voltage range is from 1.8V to 5V.

The device has a low operating power consumption, and other features include low standby current and a temperature-compensated voltage controlled oscillator (VCO) with an internal 0.3 to 1.2V control voltage range. The receiver also has a programmable linearity of up to 1 dB, ideal for applications that require frequency coverage up to 1 GHz.

Working Principle

The ATA5723CP3-TKQY works as an FM receiver and is designed with an Automatic Gain Control (AGC) to minimize signal variations. It has an internal limiter that allows it to handle amplitude modulation signals without distortion. The internal AGC also enables fast reaction times in case of any radiofrequence signal variations.

The device is designed to identify 36 different codes and consists of a high-speed frequency synthesizer, allowing fast channel scanning and frequency synthesis. It also has a 9-bit A/D converter, allowing the receiver to accurately decode signals up to 9-bit resolution.

The ATA5723CP3-TKQY also includes a carrier detector for optimal receiver performance. The carrier detector is used to detect the presence of the intended FM signal in the receiver. It performs FM demodulation by suppressing any noise or unwanted frequency variations and correcting any amplitude variations.

The receiver\'s architecture allows different types of modulation in order to optimize the data rate. It also supports many coding techniques such as Manchester Coding, Differential Manchester Coding, Biphase Coding, and Manchester Bi-Phase Coding.

Conclusion

The ATA5723CP3-TKQY is an RF receiver designed for automotive applications, including remote keyless entry systems and tire pressure monitoring systems. It has a low operating power consumption, a programmable linearity of up to 1 dB, and supports various modulation and coding techniques. The receiver is equipped with an Automatic Gain Control (AGC) for fast reaction times, and a carrier detector for optimal receiver performance.
